Pan American Silver Uncovers High-Grade Veins at La Colorada Mine — Pan American Silver Corp.

Event summary

Pan American Silver discovered at least four new high-grade veins at the La Colorada mine in Zacatecas, Mexico, with silver assays exceeding 1,000 g/t in 40% of reported drill holes.
Exploration drilling between November 2025 and January 2026 covered 17,774 meters in 38 holes, revealing wide mineralized intercepts with high silver, gold, and base metal grades.
The discovered structures indicate potential to add to the mineral resources at La Colorada, with results to be included in the mineral reserve and resource update as of June 30, 2026.
A new exploration crosscut on Level 588 and a second crosscut on Level 448 are underway to improve zone access and drill coverage.

The big picture

Pan American Silver's discovery of new high-grade veins at the La Colorada mine underscores the strategic importance of exploration in extending the life and value of existing mining operations. The findings come at a time when the mining industry is increasingly focused on resource expansion to offset declining grades and rising production costs. The success of this exploration program could position Pan American Silver as a leader in high-grade silver production, potentially attracting more investment and partnerships in the precious metals sector.
